MILK-STRAINER.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed October 22, 1912. Serial No. 727,095.

To all whom it may concern:

Be it known that I, CHARLES H. CLARK, a citizen of the United States,residing at Kalamazoo, Michigan, have invented certain new and usefulImprovements in Milk- Strainers, of which the following is aspecification. V

This invention relates to improvements in milk strainers.

The main objects of this invention are to provide an improved milkstrainer and filter which is simple in structure and operation andeasily cleaned and kept in a sanitary condition.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a side elevation of my improvement in milk strainers andfilters. Fig. II is a plan view thereon. Fig. III is a vertical centralsection on a line corresponding to line 3-3 of Fig. II. Fig. IV

j is a horizontal section on a line corresponding to line 4.-4 of Fig.III. Fig. V is a horizontal section on a line corresponding to line 55of Fig. III. Fig. VI is a bottom view, the body of the receptacle notbeing shown. Fig. VII is a detail perspective view showing one of thedetails of the filtering pad support. Fig. VIII is a perspective view ofthe clamp member 12. Fig. IX is a detail plan view of the innerreceptacle 6. Y I

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the outer receptacle 1 is preferably tapereddownward and drawn abruptly in at 2 to an open neck 3 at its lower end.Thelower end of the neck is provided with a head 4. At its of the outerreceptacle by ring 21.

upper end the receptacle 1 is provided with a flange-like rim 5. Theinner receptacle 6 is provided with a flange-like rim 7 at its upper endadapted to rest on therim of the outer receptacle. The inner receptacle6 is tapered downwardly so that there is a space between its walls andthe walls of the receptacle 1. The inner receptacle 6 is provided with ascreen bottom 8 which is supported adjacent to but spaced from the neck3 of the outer receptacle.

The neck 3 is provided with a filtering its edges between the supportand the lower end of the neck. The clamping member 12 is engaged withthe ears with its cams outwardly, the clamp member is then swung overand its cams acting on the rim clamp the support in place.

To prevent the pad being displaced by the impact or the current of milkas might occur where the pad is made of loose material, such as cottonbatting or absorbent cotton, I provide a foraminated plate 17 adapted tofit within the neck. This plate is provided with a flange 18 at itsedge, by which it is normally supported out of contact with the pad. Theplate 17 distributes the milk to the pad quite evenly. The screen 8 ofthe inner receptacle also assists in distributing the milk or otherliquid evenly to the filtering pad. This screen is preferably quite afine screen so that it collects the coarser material.

I preferably provide a cover 19 having a down turned flange 20 at itsedge adapted tovfit over the flanges of the receptacles. The cover 19 isloosely secured to the rim 5 This cover connection is of advantage inthat it does not provide unsanitary corners or creases. The rim 7 of theinner receptacle 6 is notched to receive the ring 21.

My improved strainer is easily assembled or disassembled and whendisassembled the parts are easily cleansed and kept in a sanitarycondition, that being one of the main objects of this invention.Further, my im proved strainer or filter is very effective.

I have illustrated and described my improvements in detail in the formin which I have embodied the same. I have not attempted to illustrate ordescribe various modifications in structural detail which I contemplateas being possible as such modifications will be readily understood bythose skilled in the art to which this invention relates.

Having thus described my invention, what I claim is new and desire tosecure by Letters Patent is:

1. In a strainer, the combination of an outer receptacle having aflange-like rim at its upper end and an open neck at its lower end; afilter pad support comprising a rim having a screen thereon; clampingmeans by which said support is removably secured to said neck; a filterpad arranged on said support with its edges between the end of the neckand said support; a foraminated plate having down-turned flanges at itsedges disposed within the neck upon said pad; an inner downwardlytapered receptacle provided with a screen bottom and having a rimresting on the rim of said outer receptacle, the bottom of said innerreceptacle being adjacent to but spaced from the neck of said outerreceptacle; and a cover having a flange adapted to close over the rimsof said receptacles and secured to the rim of the outer receptacle by aring, the rim of the inner receptacle being notched to receive the ring.

2. In a strainer, the combination of an outer receptacle having an openneck at its lower end; a filter pad support comprising a rim having ascreen thereon; clamping means by which said support is removablysecured to said neck; a filter pad arranged on said support with itsedges between the end of the neck and said support; a foraminated platehaving down-turned flanges at its edges disposed within the neck uponsaid pad; an inner downwardly tapered receptacle provided with a screenbottom and hav: ing a rim resting on said outer receptacle, the bottomof'said inner receptacle being adjacent to but spaced from the neck ofsaid outer receptacle.
